Instructions for basic operations of airtight containers

Container installation steps:

  1. Make sure that each liner has a Vessel Sleeve installed. At the same time, ensure that the vessel sleeve is dry.
  2. Check the rupture disk and ensure that only one rupture disk compatible with the vessel sleeve is installed in each pressure relief hole. (If there is no explosion-proof membrane, this step can be ignored).
  3. After strictly confirming that the pressure shrapnel is installed correctly (with the groove facing upwards), use auxiliary tools to lock the container to prevent leakage.
  4. Make sure that in the same batch of reactions, medium-pressure and high-pressure reaction vessels are not mixed at the same time.
  5. Installing the temperature sensor Make sure the temperature probe is fully inserted into the vessel. Incorrect installation can have serious consequences (this step can be ignored for microwave digesters without temperature sensors)
  6. In order to standardize the operation of the instrument, the pressure vessels on the turntable should be as uniform and symmetrical as possible, and the pressure vessels should be placed vertically.
  7. The pressure sensing line should be placed on the hook of the top plate, and a trial rotation of the turntable should be carried out to ensure that the temperature and pressure sensing line is not entangled. (Ignore this step if there is no temperature sensing line).
  8. For special powders and oils, please use weighing paper to send them into the tube body to prevent samples from hanging on the wall.

Steps for safe venting of containers:

A safe machine design should have temperature and pressure warnings during the reaction process and automatic cooling operation safety warnings after the end:

  1. During sample processing, the temperature and pressure change status and danger warnings are displayed in real time.
  2. When the pressure vessel is cooled and disassembled, it indicates and warns the operator of the safe state value of temperature and pressure in the vessel. Prevent accidental operation. The pressure tank can only be removed and depressurized after the indicated pressure is <50psi.

Notice

Always wear gloves, a lab coat, and safety goggles before deflation. Take out the temperature probe of the main control tank, and then slowly open the pressure relief screw cap in the fume hood to release the pressure, and the container can only be vented at room temperature.
